PAK 68/3 views ?

Post by Beric Du » Wed, 30 Nov 1994 03:08:26



Hi all,

  Has anyone tried the PAK 68/3 accelerator board on an STFM ?

  If so what is the performance/compatibility like? I know a 68030
  clocking 33 MHz is going to be fast - but what will be the effect of
  having to slow down to access the rest of the chips ?

  My current hardware is an 520STFM upgraded to 4MB, with Magic O/S,
  SCSI Hard Disk - so the only real way to upgrade is a) get an
  accelerator like PAK 68/3 or plump for a Falcon or TT. As I am not
  bothered about 2 squillion colours on screen or brilliant sound this
  would hint at a TT. Hence is it worth spending the extra 500 quid or
  so on the TT or get PAK 68/3 or similar?

  Any views would be appreciated.

I was in a similar situation. I wanted to do more C programming but was
finding memory and CPU constraints.

I looked *very* hard at the PAK/3, even to the extent of going to a show
in London to see it.

However in the long run I plumped for a second hand TT. The cost difference
between upgrading my MSTE with a PAK/3 and buying a second hand TT was not
all that much. Taking into account what I got for selling my MSTE, the
difference was very marginal.

The TT though has many extra features. TT-Hi (1280x960 paperwhite screen)
and more memory expansion (mine came with 8Mb). In your case you would also
get a VME bus and a fast serial port extra (among other things).

True - the PAK/3 is faster, especially if you have a 40 or 50Mhz version.
OTOH untill they sort out TT Fast RAM for it, a genuine TT with TT Fast
RAM actually out performs it in the tests I done (dhyrstone).

The fastram card, 'Frak030', was launched last week.

Anybody fancy doing a dhrystone test for it? I can email the dhrystone prog
that was used for the 20 or so Atari configurations people have already tested
for me.

:-)

Thanks

Roland.

PS If anybody wants a copy of the results then I am happy to email or post
them here. I just don't know how many people are actually *interested* in
them?

It wouldn't fit into the case. You'll have to change to a tower-case.

There are no compatibility problems with software, which is written
processor-independent. It's the same as with a TT. For games, of course,
the speed itself is a compatibility problem.

I'm very happy with my PAK.
